Rotating bar Bending Fatigue Testing machine

Model: UT1016A, DIN 50113, ISO 1143

DIN 50113, ISO 1143 Rotating bar Bending Fatigue Testing machine, Rotating Beam Fatigue – Pure bending moment; Rotating Bending Fatigue test equipment.


Rotating Bending Fatigue Testing Machines are intended to determine the fatigue strength (according to DIN 50113, ASTM F1160, EN 13261 and ISO 1143) in rotational bending fatigue tests of metallic or non-metallic materials. The preparation of the diagram, the comparison of the fatigue strength of different types of materials in this diagram, the effects of important parameters on fatigue strength such as notch effect and surface roughness are the basic principles of application of rotational bending fatigue tests.

1.1, This automatic Rotating Bending Fatigue Tester is used to carry out simple bending fatigue test on metal and its alloy materials at room temperature and high temperature, and to determine the fatigue performance of metal circular cross-cut interview samples when under bending stress in rotational state.

1.2, The use of simple support beam structure, by racks, AC motors and drivers, measurement and control system, loading weights, protection devices, etc. , the equipment has rotation number counter. The device is also available with various corrosion tanks to support a variety of corrosion bending fatigue tests.

1.3, The clamp adopts the elastic front and rear chuck holding specimen, the chuck and the spindle elastic barrel clamp connection, can achieve precision fit, to ensure that the radial beat of the clamping specimen meets the requirements of the navigation and national standard.


2.1, Equipped with touch screen operation and display panel for the completion of all control parameters of the setting, all measurement data display and all test operations, equipped with a network interface with computer communication, elected with the computer, can realize the computer to a single device measurement and control or the network of multiple devices, test weekcan can be set at will, to reach the set value can be automatically stopped and has power-down protection function.

2.2, Both front and rear fixtures are clamped in an elastic cone sleeve for a sample, enabling precision fit.

2.3, ple break automatic shutdown protection, etc., equipment equipped with transparent housing, the test process can be unattended.
